Google Mesh & ATT Fiber

[Khyer]

Have 4 google WiFi AC1200 2x2 pucks connected to ATT fiber BGW320-500 Fiber modem with on board access point. Configuration is combination of LAN & WAN to provide coverage over 3600 sq ft & three floors of house. Have BGW configured to same SSID/PWD as the Mesh units. Two AC1200s are LAN-SwitchAC1200-Lan-SwitchAC1200 the rest are WAN connections to rest of structure. The LAN piece runs across the house to link office to fiber entry point.

In some areas I am not satisfied with WAN speeds. A few feet from an alleged "excellent" connection I get only 90 Mbps in a WiFi speedtest on iPhone 11. Only two of use in the house, no kids, no bandwidth hogging in/out like gaming, media streaming etc.

Any recommendations to configuration would be welcome.

By WAN (wide area network) you probably mean WLAN (wireless local area network)?

First potential problem is that you're running double NAT. This can cause performance issues and strange problems. Best practice is to disable the router functionality in the ISP equipment.

Second, it seems like you are running a combination of wired and wireless backhaul/connection between Nest Wifi units. This is not recommended, as it also can cause problems and strange behavior. Either go all wired, which will give the best reliability and performance, or all wireless.

If you can't or won't pull ethernet cable to all the Nest Wifi units, maybe ethernet over coax (MoCA) or powerline can be used?

Here's a diagram on how wired backhaul can be done properly:
